Waste bin assembly

ABSTRACT

A waste bin assembly for sorting and emptying of wastes disposed therein is disclosed. The waste bin assembly comprises at least two compartments which are hung on a vertical shaft that is mounted beneath a work table and rotatable by means of a bearing and mounting arrangement at the upper end of the shaft. The compartments are detachably hung on the shaft.

The present invention is for a waste bin with an option of wastesorting.

Waste bins for collecting of wastes of various kinds are used at mostplaces of work and at many other places. It is then desirous that thewastes can be sorted into at least two fractions. For reasons of spaceavailability this is often unsuitable or impossible which means that thewastes are put unsorted into the same container with the accompanyingdisadvantages.

The invention may be said to be a recovery and waste station within aminimal space at a local place of work. The object of the presentinvention is a waste bin which can be emptied and enables sorting ofwastes into at least two fractions and which may be used even at minimalspaces. One fraction may be burnable and recoverable paper while theother fraction includes other wastes such as plastics, tape, fruit peeletc. It is another object of the invention that all collectingcompartments which are parts of the waste bin shall be made easilyaccessible when the respective kind of waste shall be disposed of. Afurther object of the invention is that it shall be possible to mountthe waste bin on to the underside of a work table or the like so thatfloor space is saved. The waste bin of the invention has thecharacteristics which are apparent from claim 1, embodiments of theinvention have those characteristics which are apparent from the otherclaims.

The invention will below be described with reference to the example ofan embodiment thereof which is shown in the enclosed figures.

FIG. 1 shows a waste bin according to the invention which is mountedunder a work table.

FIG. 2 is a blow up of parts of the means for bearing and mounting.

FIG. 3 is a cross-sectional view of the central shaft taken at SectionA—A of FIG. 2.

The device comprises a central shaft 1 made from tubular square hollowprofile which is arranged vertically. On each side of the square profilethere are several through bores 11 for the hanging up of boxes orcompartments 9, 10. Although two boxes are shown by way of example, theshaft may also support the hanging of more than two compartments orboxes. The boxes are easily detachable by being hooked at the openingsin a suitable way.

Fixed to the upper end of the shaft 1 by welding or otherwise there is aplate 2 having a central hole for a bolt 6. The bolt is a shaft for anaxial bearing 4 and it is at its upper end mounted at a mounting plate 8by means of a locknut 7. A sliding plate 5 is arranged between themounting plate 8 and the plate 2. The mounting plate 8 has a suitablenumber of holes for fastening by means of screws on the underside of aworktable 3.

Other varieties and embodiments are possible within the frame of theinventive idea. For example the shaft may instead of being a tubecomprise several, vertical bars at which the boxes are hung up. Thenumber of boxes may vary but two boxes is often sufficient for normaloffice use.

1. A waste bin assembly mountable only to an underside of an elevatedwork surface for receiving and accommodating waste deposited into theassembly such that the waste bin assembly is suspended entirely from theunderside of the elevated work surface without additional support froman underlying floor surface above which the work surface is elevated,said waste bin assembly comprising: a plurality of waste-receivingcompartments each configured and disposed for accommodating articles ofwaste selectively depositable by a user into said each compartment; amounting unit constructed and positioned for securement of the mountingunit directly to the underside of the elevated work surface forsuspending the plural waste-receiving compartments from the elevatedwork surface; an elongated shaft extending from the mounting unit at oneend of the shaft to the plural waste-receiving compartments at anopposite end of the shaft, said plural waste-receiving compartmentsbeing detachably secured to said shaft so as to suspend the pluralwaste-receiving compartments on the shaft from the underside of theelevated work surface such that the waste bin assembly and the shaftopposite end are suspended in hanging relation from the underside of theelevated work surface without direct support of the waste bin assemblyfrom the underlying floor surface above which the work surface iselevated; and a bearing in said mounting unit for enabling selectiveaxial rotation, relative to the mounting unit, of the shaft and, withsaid shaft, of the plural waste-receiving compartments detachablysecured to the shaft for facilitating enhanced user access to selectedindividual ones of the plural waste-receiving compartments throughselective user-rotation of the shaft relative to the mounting unit andthe underside of the elevated work surface to which the mounting unit issecured.
 2. A waste bin assembly bin accordance with claim 1, whereinsaid elongated shaft comprises a hollow tube having a substantiallysquare cross-section.
 3. A waste bin assembly bin accordance with claim1, wherein each of said plural waste-receiving compartments isindividually detachable from said shaft for selective emptying of saideach compartment of waste articles accommodated in said eachcompartment.
 4. A waste bin assembly in accordance with claim 1, whereinsaid elongated shaft comprises a hollow tube that includes a pluralityof bores defined therein for detachable hooked engagement of saidwaste-receiving compartments with said bores.
 5. A waste bin assemblybin accordance with claim 1, wherein each of said waste receivingcompartments includes an opening through which articles of waste areselectively depositable into said each waste receiving compartment, andwherein said mounting unit is disposed, when the waste bin assembly issecured for use to the underside of the elevated work surface, in spacedrelation above said openings of said plural waste receivingcompartments.
 6. A waste bin assembly in accordance with claim 1,wherein each of said waste receiving compartments includes an openingthrough which articles of waste are selectively depositable into saideach waste receiving compartment, and wherein said elongated shaft oneend extends, when the waste bin assembly is secured for use to theunderside of the elevated work surface, above and beyond said openingsof said plural waste receiving compartments.
